Une unité de mémorisation de valeurs d'énergie réelles (35a) mémorise des informations sur des valeurs réelles de consommation d'énergie d'un appareil d'équipement pour chaque intervalle de temps d'un premier jour spécifié. Une unité de mémorisation d'historique d'exécution de commande DR (35b) mémorise des informations d'historique d'exécution de commande DR qui indiquent, pour chacun des intervalles de temps correspondant aux valeurs réelles mémorisées par l'unité de mémorisation de valeurs d'énergie réelles (35a), si une commande DR a été exécutée pour l'appareil d'équipement sur la base d'informations relatives à des demandes de commande DR et/ou d'informations relatives au coût de la consommation d'énergie. Une unité de calcul de valeur d'énergie virtuelle (36a) utilise les informations sur les valeurs réelles du premier jour spécifié pour calculer, afin de remplacer les valeurs réelles des intervalles de temps où la commande DR a été exécutée, qui sont mémorisées par l'unité de mémorisation d'historique d'exécution de commande DR (35b), ou les valeurs réelles de périodes qui incluent lesdits intervalles de temps et qui sont concernées par la commande DR, une valeur complémentaire de la consommation d'énergie de l'appareil d'équipement comme si la commande DR n'avait pas été exécutée.
